Elements Of Partial Differential Equations By Ian Sneddon Pdf Free 13 !EXCLUSIVE!

this thesis contains four chapters. the first chapter is an introduction to the theory of differential equations and to their approximations. we will show that the problem of the approximate solution of differential equations is equivalent to the problem of the approximate solution of differential-algebraic equations.

this theory, which goes back to newton, has been developed since then. the classical methods for solving differential equations are discussed. the most important methods are first and second order taylor approximations, padé approximation and the method of successive approximations.

another important problem is the theory of linear differential equations. the linear theory is the most important in the theory of differential equations. it is a very old theory and it is very useful in many applications. we will discuss a generalization of the linear theory to nonlinear equations. we will show that the theory of nonlinear equations is a generalization of the theory of linear equations. in this case the nonlinear equations are described by a function f(f) that depends linearly on its argument.

linear elliptic problems for a second order partial differential operator in two dimensions with a constant coefficient are treated. the analysis is based on a fundamental theorem of b. r. fitzpatrick and l. scott on the unique solvability of boundary-value problems in a class of banach algebras. problems that are solvable by the method of fundamental solutions are presented. an application of the theory to the two-dimensional case of the laplace equation with dirichlet boundary conditions is given. the theory is illustrated by analyzing the eigenvalue problem for a particular case of a buckling problem. the well-known buckling problem of a thin rod is reexamined by using the method of fundamental solutions. the solution to the buckling problem is found. furthermore, a solution is presented for the double-obstacle problem. for the single-obstacle problem, the solution is also given, and an application of the theory to the buckling of a thin plate is shown. moreover, the two-dimensional case of the laplace equation with neumann boundary conditions is studied.
